Below is a bedroom that also borrowed from the color wheel's triadic theory for it's scheme, using primary colors as well.
This cozy little hide away below uses red, yellow-green, and blue-green in it's split complmentary scheme.
Below is a bedroom that also borrowed from the color wheel's triadic theory for it's scheme, using primary colors as well.

The room pictured above has a color scheme based on violet as the middle color flanked by blue-violet and red-violet.
In my opinion the room below is a color scheme of red-violet flanked by red and violet, because there is no blue in this room.
I could go on and on finding pretty pictures so I'll move on to monochromatic.
I think a lot of people hear monochromatic and think neutral colors so I went the total opposite way and choose rooms full of COLOR to display monochromatic color schemes.
I can't decide if the image below is a blue or a blue-green monochromatic palette, I keep referring back to my color wheel and I'm leaning towards blue-green, what do you think?

The next two images I really had fun with finding. I wanted to display how easily going from one monochromatic scheme do the next could alter the way a room looks and the colors used in the room.
Below we have a room that has a monochromatic scheme built on yellow-orange (top) and one built on orange (bottom) TOTALLY DIFFERENT!
They also look different because the rooms vary in style, but there is no denying that the color difference is dramatic from one to the next.

Ahhh the joy of color.
If you still hadn't found a combination of colors that you like...don't fret, I'll post about another theory tomorrow.
Catch ya'll later!
